Julianne Moore has admitted the Oscar buzz surrounding her latest film is "lovely".

The flame-haired actress braved the cold in London's Leicester Square at the BFI London Film Festival for the premiere of The Kids Are All Right, which is tipped for Academy Awards success.

She told reporters: "We're so grateful for the attention. It's so nice when people respond to your work and see the movie. So yes, it's lovely."

Julianne, who wore a teal figure-hugging dress and spike heels, took time to greet fans and pose for photographs on the red carpet.

The film centres on lesbian partners Nic (Annette Bening) and Jules (Julianne), whose relationship runs into problems when children Joni (Mia Wasikowska) and Laser (Josh Hutcherson) decide to track down their biological father Paul (Mark Ruffalo).

Julianne said: "It's something we all understand too because most of us come from families. It's something that's incredibly relatable, not just as a parent but as a child."

She added that the movie "reflects popular culture", saying: "I don't think this movie would exist if there weren't families like this all over the world."

Director Lisa Cholodenko also attended the event, as did Mark, who brought along his wife Sunrise Coigney.
